Full-Sized Humanoid Platform | Last verified: 2026-02-02

A) Short Overview

The Fourier Intelligence GR-1 is a full-sized humanoid robot platform designed for general-purpose research and application development in human-centric indoor environments.

Official Scope & Positioning:

R&D Platform: Aimed at robotics and embodied AI development within research and educational sectors.
Industrial Exploration: Positioned for scenarios such as inspection, logistics, and task assistance.
Vision-Centric: Features a platform-level integration for vision-based perception and humanoid workflows.

Commercial Availability:

The GR-1 is available through enterprise procurement via direct inquiry. Fixed “off-the-shelf” prices and delivery terms are not publicly stated.

B) Key Facts

Category	Fourier Intelligence GR-1	Notes / Variant

Note on Discrepancies: There is an internal conflict regarding torque (230 N·m vs 300 N·m reported in press items) and runtime phrasing (45–60 min walking vs. 2 hours total). These should be clarified in a formal quote.

C) Capabilities & Limits

Verified Capabilities (Can):

Vision-Based Perception: Utilizing multiple RGB cameras for spatial awareness and environmental interaction.
Developer Access: Availability of an Actuator SDK (Python/C++) for low-level and high-level development.
Framework Support: Official documentation confirms support for ROS 2.

Known Constraints (Limits):

Runtime Inconsistency: Battery endurance is highly dependent on the task profile (walking vs. idling).
Payload Constraints: The 3 kg hand payload is confirmed, but broader load-bearing limits are not specified.
Environmental Protection: No official IP rating or formal safety certifications are mentioned in the primary documentation.

D) Verified Deployments

As of February 2, 2026, no independently verified large-scale industrial deployments have been documented. The platform remains primarily in the R&D and pilot exploration phase.

E) BotReburn Trust Note (Procurement Guidance)

Inquiry Protocol: Procurement is inquiry-based; ensure a written commercial offer includes clear support SLAs and spare parts availability.
Endurance Validation: Validate real-world battery performance for your specific use case (e.g., continuous walking vs. stationary manipulation).
Safety Sensing: Confirm if LiDAR or additional safety sensors are included, as only RGB cameras are listed in the standard datasheet.
SDK Licensing: Clarify licensing and update policies for the Actuator SDK before production-level deployment.
Controlled Environments: Due to the unknown IP rating, deployments should be limited to lab or controlled indoor settings until further documentation is provided.
